Description

Technical Field

[0001] The invention relates to a medical detection instrument, in particular to a test tube placing rack. Background Art

[0002] A test tube rack is an instrument specially used for chemical experiments. Its main function is to provide an orderly placement space for test tubes. In the laboratory, test tube racks are usually placed in an inclined or vertical manner for easy management and use. Among them, the inclined test tube rack is mainly used to control the moisture in the inverted test tube to ensure the dryness and cleanliness of the inside of the test tube. The vertical test tube rack is convenient for observing the reaction inside the test tube, so that the experimenter can see the changes in the test tube more clearly.

[0003] In chemical experiments, test tubes often need to be added with various additives and then tilted to observe the reaction inside. This operation is very common in chemical experiments. For example, when conducting an acid-base color change experiment, the solution in the test tube will change color due to changes in acidity and alkalinity. By tilting the test tube rack, this change process can be observed more intuitively.

[0004] However, most of the test tube racks currently on the market are manually operated and lack automation functions. This means that the experimenter needs to manually add additives and manually tilt the test tube rack to observe the reaction. Although this manual operation meets the experimental needs to a certain extent, in some cases, manual operation may lead to low experimental efficiency and may even affect the accuracy of experimental results due to improper operation.

[0005] Therefore, there is an urgent need in the market for a test tube placement rack that can automatically add additives and automatically tilt and place test tubes. Summary of the invention

[0006] The present invention provides a test tube rack, which can greatly improve experimental efficiency, reduce errors caused by human operation, and make the experimental process more accurate and efficient. Through the application of automation technology, the experimenter can focus more on the analysis of experimental data and the interpretation of experimental results, thereby promoting the further development of chemical experimental research. The specific scheme is as follows:

[0007] A test tube display rack, the test tube display rack comprising:

[0008] The bracket is provided with a vertical frame, and a dropper is installed on one side of the top of the vertical frame;

[0009] A display rack, the display rack is installed on the bracket, and a slide groove is provided on the upper surface of the display rack;

[0010] A test tube placement component is slidably installed in the slide groove. The test tube placement component is provided with a vertical area and an inclined area. Both the vertical area and the inclined area are provided with at least one test tube slot. The test tubes placed in the test tube slots in the vertical area and the inclined area are in a vertical state and an inclined state respectively.

[0011] The driving device is connected to the test tube placing assembly, and the driving device drives the test tube placing assembly to move along the slide slot, so that the openings of the test tubes placed in the vertical area or the inclined area pass directly under the dropper in sequence.

[0012] Furthermore, an inclined turning area is provided between the vertical area and the inclined area, and a test tube slot is provided in the inclined turning area.

[0013] Furthermore, the test tube placement assembly includes a plurality of test tube placement blocks, and a test tube slot is provided in the middle of the top of the test tube placement block.

[0014] The test tube placement block is transversely penetrated with a through hole, and a plurality of groups of test tube placement blocks are connected in series by elastic ropes passing through the through holes to form a test tube placement assembly.

[0015] Furthermore, the slide trough and the test tube placement assembly are in the shape of a bar or a ring.

[0016] Furthermore, a rubber layer is bonded to the outer side of each test tube placement block;

[0017] The driving device consists of a roller, a driven wheel, a belt and a motor. The roller and the driven wheel are installed at intervals on the same side of the placement frame. The output end of the motor is fixedly installed with a roller. The roller and the driven wheel are connected by a belt transmission. The belt and the rubber layer roll and frictionally cooperate, and the rotating belt drives the test tube placement assembly to slide along the direction of the slide groove.

[0018] Further, the bracket includes a mounting base fixedly connected to the bottom of the vertical frame;

[0019] A dropper bracket for fixing the dropper is fixedly installed on the top of the vertical frame, an additive medicine tank is installed on the dropper bracket, the additive medicine tank is provided with a micro pump body, a connecting port is provided on the top of the dropper, and the connecting port is connected to the additive medicine tank through a conveying pipeline.

[0020] Furthermore, a stepped through hole connected to the test tube slot is provided at the bottom of the test tube placement block;

[0021] The test tube placement rack also includes a control component connected to the driving device and the micro pump body, and the control component includes a control circuit, an elastic switch arranged in the step through hole, and a contact switch arranged on the placement rack;

[0022] The elastic switch comprises a plastic rod penetrating the step through hole, one end of the plastic rod located in the test tube slot is connected to an arc-shaped pad, the other end of the plastic rod is provided with a metal sheet, a baffle located between the arc-shaped pad and the metal sheet is fixed to the inner wall of the step through hole, and a spring located between the baffle and the arc-shaped pad is sleeved on the plastic rod;

[0023] The contact switch includes a switch connecting piece arranged at the bottom of the chute and directly below the dropper, and the switch connecting piece is connected to the control circuit.

[0024] After the metal sheet contacts the switch connecting sheet, the switch connecting sheet forms a path to trigger the control circuit, and the control circuit turns off the driving device and starts the micro pump body.

[0025] Furthermore, the metal sheet is provided with an upwardly bent flip surface at both ends of the sliding direction.

[0026] The switch connecting piece is provided with a second downwardly bent flip surface at both ends in the sliding direction.

[0027] The advantages of the present invention are:

[0028] 1. The test tube placement component can simultaneously place two groups of test tubes in different states, vertical and tilted, to meet various test requirements;

[0029] 2. Through the elastic switch and contact switch, the test tube can automatically stop when it turns to the bottom of the dropper and inject the medicine by the dropper. Whether the test tube is placed vertically or tilted, the medicine can be automatically injected, which reduces the manual operation of the experimenter, improves the experimental efficiency and effectively avoids misoperation;

[0030] 3. When the test tube placement block passes under the dropper without load, the elastic switch will not be turned on because it is not pressed by the test tube above. This ensures that the test tube placement block without load will not stop when passing under the dropper until the next test tube is inserted and the contact switch is triggered and stops, thus improving the experiment;

[0031] 4. The design of the test tube rack makes it take up little space, which is convenient for flexible placement in the laboratory, while ensuring the stability and safety of the test tubes;

[0032] 5. Easy to maintain: The various components of the test tube rack are simply designed and easy to disassemble and clean, ensuring reliability for long-term use.

[0033] In summary, the test tube display rack of the present invention not only improves the efficiency and accuracy of chemical experiments, but also has the advantages of simple operation, safety and reliability, and is very suitable for use in various chemical experiments.

[0046] In order to fully understand the present invention, detailed steps and detailed structures will be proposed in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0047] Embodiment 1

[0048] Reference Figure 1-7 As shown, the present invention provides a test tube placement rack, which mainly includes a placement rack 100, a test tube placement component 200, a control component 300, a bracket 400, and a driving device 500.

[0049] Bracket 400

[0050] like Figure 1 As shown, the bracket 400 includes a mounting base 440 and a vertical area 110 mounted on the top of the mounting base 440. A dropper bracket for fixing a dropper 430 is mounted on one side of the top of the vertical area 110. An additive medicine tank 410 is mounted on the dropper bracket. The additive medicine tank 410 is provided with a micro pump body. A connection port 420 is provided on the top of the dropper 430. The connection port 420 is connected to the additive medicine tank 410 through a delivery pipeline. The additive medicine tank 410 can automatically deliver medicine to the dropper 430 through the micro pump body.

[0051] Display rack 100

[0052] like Figure 1-4 As shown, the display rack 100 is installed on the bracket 400 , and an annular slide groove is provided on the upper surface of the display rack 100 , and one end of the annular slide groove is located directly below the dropper 430 .

[0053] Test tube display assembly 200

[0054] like Figure 2-5As shown, the test tube placement assembly 200 is slidably installed in the slideway, and the test tube placement assembly 200 is provided with a vertical area 110 and an inclined area 120, and an inclined turning area 130 is provided between the vertical area 110 and the inclined area 120 for transition, and the vertical area 110 and the inclined area 120 are both provided with a plurality of test tube placement blocks 210, and the inclined turning area 130 is provided with a test tube placement block 210, and a test tube slot 220 is provided in the middle of the top of each test tube placement block 210. Among them, the test tubes placed in the test tube slots 220 of the vertical area 110 are in a vertical state, and the test tubes placed in the test tube slots 220 of the inclined area 120 are in an inclined state. The direction of the test tubes in the test tube slots 220 of the inclined turning area 130 can be determined according to the situation, and can be vertical or inclined. By controlling the opening angles of the test tube slots 220 in the vertical area 110, the inclined area 120, and the inclined turning area 130, the test tube placement blocks 210 in either the vertical area 110 or the inclined area 120 pass under the dropper 430, and the test tube opening inserted at the top of the test tube placement block 210 is located directly below the dropper 430.

[0055] Through holes 230 are provided transversely on both sides of each test tube placement block 210 , and all the test tube placement blocks 210 are connected in series in sequence by elastic ropes 240 passing through the through holes 230 to form a test tube placement assembly 200 that can rotate in the slide groove of the placement rack 100 .

[0056] In an optional embodiment, the test tube placement block 210 is a fan-shaped block, which can better match the annular slide groove and slide therein. A rubber layer 260 is bonded to the outside of each test tube placement block 210. In addition, an inverted "T"-shaped step through hole 250 connected to the test tube slot 220 is provided at the bottom of the test tube placement block 210.

[0057] Driving device 500

[0058] like Figure 1 As shown, the driving device 500 is composed of a roller, a driven wheel, a belt and a motor. The roller and the driven wheel are installed at intervals on the same side of the display rack 100. The output end of the motor is fixedly installed with a roller. The roller and the driven wheel are connected by a belt transmission. The belt and the rubber layer 260 are in rolling friction cooperation, thereby realizing that the rotating belt drives the test tube display assembly 200 to slide along the slide groove direction.

[0059] Control Components 300

[0060] like Figure 6-7 As shown, the control component 300 is connected to the driving device 500, and the control component 300 includes a control circuit, an elastic switch and a contact switch.

[0061] The elastic switch includes a plastic rod 310 that passes through the step through hole 250. One end of the plastic rod 310 located in the test tube slot 220 is connected to a concave arc-shaped pad 320. The other end of the plastic rod 310 is provided with a metal sheet 350. The inner wall of the step through hole 250 is provided with a baffle 340 located between the arc-shaped pad 320 and the metal sheet 350. The plastic rod 310 is sleeved with a spring 330 located between the baffle 340 and the arc-shaped pad 320.

[0062] The contact switch includes a switch connecting piece 360 ​​which is arranged at the bottom of the slide groove of the display rack 100 and is located directly below the dropper 430. The switch connecting piece 360 ​​is an open-circuit switch connected to the control circuit. The control circuit is connected to the driving device 500. When the metal sheet 350 contacts the switch connecting piece 360, a passage is formed in the switch connecting piece 360. After receiving the electrical signal, the control circuit promptly turns off the rotation of the motor of the driving device, and then starts the micro pump body of the additive tank 410 to transport the additive to the dropper 430.

[0063] When the test tube is inserted into the test tube slot 220, the test tube slot 220 presses the arc-shaped pad 320 downward, so that the plastic rod 310 overcomes the resistance of the spring 330 and slides downward, thereby making the metal sheet 350 and the switch connecting sheet 360 form electrical contact. The concave arc-shaped pad 320 can fit the bottom contour of the test tube well, and better apply force to the plastic rod 310.

[0064] In an optional embodiment, the metal sheet 350 is provided with an upwardly bent flip surface 1 351 at both ends of the sliding direction, and the switch connecting sheet 360 is provided with a downwardly bent flip surface 2 361 at both ends of the sliding direction. Both the flip surface 1 351 and the flip surface 2 361 are elastic spring sheets, and the bending design of the flip surface 1 351 and the flip surface 2 361 cooperate to effectively prevent the metal sheet 350 from contacting the switch connecting sheet 360 during the sliding process and causing a stuck phenomenon, and at the same time, better electrical contact between the two can be ensured.

[0065] The working principle of the present invention is as follows:

[0066] The additive medicine tank 410 is connected to the connection port 420 through an external hose. A person skilled in the art electrically connects the additive medicine tank 410, the driving device 500, and the switch connecting piece 360 ​​to an external control circuit and a power supply, inserts the sampled test tube into the test tube slot 220 of the test tube placement block 210, and starts the driving device 500 to drive the test tube placement assembly 200 to move on the placement rack 100.

[0067] Insert the test tube into the test tube placement block 210, and the test tube presses the arc pad 320 downward under the action of gravity, so that the plastic rod 310 at the bottom of the arc pad 320 moves downward. When the test tube placement block 210 moves to the bottom of the dropper 430 through the driving device 500, the metal sheet 350 contacts the switch connecting piece 360, so that the switch connecting piece 360 ​​forms a passage. The control circuit receives the signal and stops the driving device 500, so that the test tube is directly under the dropper 430 and no longer moves. At this time, the test tube placed on the test tube placement block 210 is exactly under the dropper 430. Then the external control circuit starts the additive medicine tank 410 to quantitatively inject the additive into the test tube through the dropper 430.

[0068] After the additive injection is completed, the control circuit starts the driving device 500 again and drives the test tube placement assembly 200 to rotate, and the process is repeated over and over again, so that the drug addition work of all the vertical and inclined test tubes placed on the test tube placement assembly 200 can be automatically completed. It should be noted that in order to realize the automatic processing of the above control circuit, those skilled in the art can easily realize it by using an editable logic circuit, but this does not belong to the protection content of this patent, and the detailed automation solution will not be repeated here.

[0069] If no test tube is inserted into the test tube slot 220 of the test tube placement block 210, the plastic rod 310 moves upward to its original position under the action of the spring 330. Even if the unloaded test tube placement block 210 moves below the dropper 430, the metal sheet 350 at the bottom of the plastic rod 310 will not come into contact with the switch connecting sheet 360, and the driving device 500 will continue to operate normally until the test tube placement block 210 with a test tube inserted moves below the dropper 430, at which time the driving device 500 will stop.

[0070] The driving device 500 pushes the test tube placement assembly 200 to push the test tube placement block 210 from the vertical area 110 through the inclined turning area 130 into the inclined area 120, and the technicians in this field turn off the power supply and wait to observe the state inside the test tube in the inclined state.

[0071] Embodiment 2

[0072] like Figure 8 As shown, the difference between this embodiment and the first embodiment is that the slide groove on the upper surface of the display rack 100 is designed to be strip-shaped, and accordingly, the test tube display assembly 200 is also designed to be a snake-bone structure that slides in the strip-shaped slide groove, and the test tube placement blocks 210 in the vertical area 110, the inclined turning area 130, and the inclined area 120 are sequentially connected in series through the elastic rope 240. The rest of the structure is basically the same and will not be described in detail here.

[0073] Compared with the technical solution of the first embodiment, the strip-shaped display rack can be set according to the inclined turning area 130 by those skilled in the art to achieve the forward or backward flipping of the test tube placement block 210.

[0074] In summary, the present invention adopts the above structure, and the advantages are:

[0075] 1. Additives can be added automatically. The additive medicine tank is connected to the dropper through an external hose. The sampled test tube is inserted into the test tube slot of the test tube placement block. The driving device is started to drive the test tube placement assembly to move on the placement rack. The test tube placement block with the test tube inserted presses the arc pad down, so that the plastic rod at the bottom of the arc pad moves downward. When the test tube placement block moves to the bottom of the dropper through the driving device, the metal sheet contacts the switch connecting sheet, and the driving device is powered on to stop working, so that the test tube is directly under the dropper. Then the external control circuit starts the micro pump body to inject the additive into the test tube through the dropper.

[0076] 2. If the test tube is not inserted, the metal sheet inside the test tube placement block will not contact the switch connection sheet, and the drive device will operate normally, preventing mis-addition and improving work efficiency;

[0077] 3. It has the effect of automatically tilting the test tube. One section of the display rack is set as a vertical area, and when the test tube display assembly is in the groove of the vertical area, it is in a vertical direction; the other section of the display rack is set as an inclined area, and when the test tube display assembly is in the groove of the vertical area, it is inclined toward the front end; an inclined turning area is set between the vertical area and the inclined area, and the driving device pushes the test tube display assembly to push the test tube placement block from the vertical area through the inclined turning area into the inclined area, and the power is turned off by technical personnel in the field, and wait to observe the state of the inside of the test tube in the inclined state.

[0078] The above describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present invention without departing from the scope of the technical solutions of the present invention, or modify them into equivalent embodiments of equivalent changes, which does not affect the essential content of the present invention. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solutions of the present invention are still within the scope of protection of the technical solutions of the present invention.
